00:00 By now we have seen in this series, most of the common operators for transformation, filtering, and combination. In my opinion, the operators we saw, like combine latest, merge, take, skip and first, and many others are operators that you're going to be dealing with very often when handling RxJS code.

00:19 There are some variants that we didn't cover, like distinct has these variants, but in those cases the variant is either easy to understand if you know the others or they are very simple and don't require too much learning, like ignore elements is very simple and single as well.

00:35 There are however other important categories of operators that we didn't cover like the operators for higher order observables, like in CAT map, merge map, and switch map. These deserve a dedicated series of lessons. Also, operators related to RxJS subjects, the so-called multicasting operators are an entirely different category of operators from what we saw. But rest assured the operators we saw are the bread and butter of RxJS and have a lot of power for handling asynchronous JavaScript.
